The next step is to set it up to who the drop should be visible to, and what restrictions the drop should have.

• Only allow buying what is made available from production orders: Here an order can be made with the quantity that is made available from the production order. This would mainly be used if you have production order made that you want to sell ahead from. In this case, it will not be possible to place an order on more than what is made available from the production order. (please see the article made about sell ahead) 
  
  
• Allow buying unlimited: Here an order can be made on an unlimited number of the product, there is no limit. This is often/mostly used when selling preorders.
